Research Tuesday reveals that lax password habits are leaving a quarter of people in serious danger of falling victim to online fraud. Online security specialists McAfee released survey findings to coincide with National Identity Fraud Prevention Week suggesting that nearly one in four people in Europe are at risk from online fraud. Almost half (43 percent) of the 3,500 respondents to McAfee's survey never change their password, increasing the risk of giving away their complete identity should that password be hacked or stolen.
